AN GULARLY ADJUSTABLEf HANDLE` HAND SAVYS` Irving, Kolodner, Brooklyn,and@Ioseplrlilinvesi,y l

This invention' relates to newfiand useful im@ provenrentszi'nauniversal handsa'w;

MoreV particularly, the invention proposesthe construction of animproved universal hand saw which ischaracterized by a handle forsupporting thek blade of said saw; and said ha-ndle consisting of' afront section attached" to` said blade and a back section adjustablyconnected with the front section in a certain way.

More specifically, the invention proposes to provide the front sectionwith a stud which engages through the back section, and proposes to formthe adjacent faces of the sections with complementary inter-engagingserrations radially of said stud, and furthermore proposes to provide awing nut threadedly mounted on the stud for clamping said sectionstogether.

The invention also proposes a modified form. In the modied form it iscontemplated to provide a latch for releasably connecting the backsection of the handle with the stud to hold it against longitudinalmotion while permitting relative turning thereof.

For further comprehensions of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the `accompanying drawing forming a material part of this disclosure:

Fig. 1 is a side elevational view of a universal hand saw constructed inaccordance with this invention.

Fig. 2 is a fragmentary sectional view taken on the line 2--2 of Fig. 1.

Fig. 3 is a transverse sectional view taken on the line 3--3 of Fig. 1.

Fig. 4 is a fragmentarxT side elevational view of a universal hand sawconstructed in accordance with another form of this invention.

Fig. 5 is a fragmentary vertical sectional view taken on the line 5--5of Fig. 4.

The universal hand saw, in accordance with this invention, includes fasaw blade I of yany design and construction. A handle II is provided forsaid saw blade. This handle consists of a iront section I2 and a backsection I3 adjacent said front section.

The front section I2 of the handle I I is formed with a slot Id extendedinwards from its front end. A clamp screw I is engaged through the frontend of the section I2 for releasably holding the saw blade I0 inposition.

A stud I6 is turnably mounted upon said front 2l 1 sectfitm'i I2 andengages through: a passage inthe back' section I3: Thefront sectionLNds-provided withl' a threaded' bushing IIiY for`V receiving the'Lthreaded-front' endI I-8L of th'e'studfel Therbacl y end of'V the studIl is aiscrprovidedg with'- threads which' are engagent by' a wing nutI9' forn holding the sections' I'2i and-:I3 clampeclitogetlier.Al'wasli' er 2U is located beneath the wing nut I9.

The adjacent faces of the sections I2 and I3 of said handle II areformed with complementary interengaging serrations 2| extending radiallyof the stud I6.

The operation of the improved hand saw is as follows:

The wing nut I9 may be loosened and the back section I3 may be turned tovarious positions upon the stud I6. When the wing nut is screwed downtight the serrations will re-engage each other, holding the handle I3 aspositioned.

In Figs. 4 and 5 a modied form of the invention has been disclosed whichis very similar to the prior form, distinguishing in the fact thatresilient means in the nature of a spring 23 is interposed between thewasher 20 of the wing nut I9 and the back section I3. More specically,the back section I3 has a recess 24 in which the spring 23 engages. Alatch 25 releasably connects the back section I3 with the stud I6restraining the back section I3 from moving longitudinally rearwards.The latch 25 includes a bolt 2B having a collar 21 against which aspring 28 abuts, The spring 28 is contained Within a recess 2S formed inthe side of the back section I3. The spring 28 acts against a plate 30mounted across the recess 29. The bolt 2B extends from the plate 30 andis provided with a head 3| by which it may be manually pulled out ashort distance. The inner end of the bolt 26 engages a groove 32 formedaround the stud I6. In other respects this form of the invention issimilar to that previously shown and like reference numerals identifylike parts in each of the several views.

The latch 2'5 may be opened by manually Dulling the head 3l a shortdistance to disengage the bolt 26 from the recess 32. Then the backsection I3' may be moved longitudinally rearwards slightly compressingthe spring 23 and disengaging the serrations ZI. The back section I3 maynow be turned to selected rotative positions. When released, the spring23 will urge the back section I3' forwards and the latch 25 willreengage the recess 32, locking the back section 35 in its new position.f

While we have illustrated and described the preferred embodiments of ourinvention, it is to 3 be understood that we do not limit ourselves tothe precise constructions herein disclosed and the right is reserved toall changes and modifications coming Within the scope of the inventionas dened in the appended claim.

Having thus described our invention, what we claim as new and desire tosecure by United States Letters Patent is:

A universal hand saw having a saw blade formed with a handle ot separatesections including a front section attached to said blade and from whicha stud extends and upon which a back section is rotatively mounted, andmeans for holding said back section in selected turned positionsrelative to said front section, comprising interengageable serrationsbetween the adjacent faces of said sections for holding the back sectionagainst turning when engaged, a nut mounted on the end of said studprojected beyond the back of said back section, a spring mounted on saidstud and operating between the adjacent faces vof said nut and backsectionA urging said back section towards said front section causing theserrations-to engage each other, whereby the back section may be movedfrom said front section against the action of said spring disengagingsaid serrations freeing said back section to be turned relative to saidfront section, and means for holding said back section against movingaway from said front section, comprising a bolt on said back sectionengageable with a complementary groove formed in said stud, andresilient means urging said bolt to maintain an engaged position withsaid groove, whereby the bolt may be pulled free of the groove freeingsaid back section.
